Be it known that I, Monats W. JAcor, acitizen of the United States, residing 'at Wehawken Heightseounty o Hudsomand State of New Jersey, have invented a new and Improved Bakers Oven, ofwhich; the following is a specication.

This invention relates to a bakers ovenfof novel construction, which possesses Superior] heating qualities, may be readily freed from soot, and carriesol the steam emitted from'. the Ibaking chamber into the bakery, so that the atmosphere of the latter is greatly improved.

In the accompanying drawing: Figure 1 is-a longitudinal section on line lfL-l, Fig. 3,'

The baking chamber 10 of theloven is disposed door 11 hung inthe front wall 12, which may be provided with dead air spaces 13... Below the oven/sole are 4shown to be arranged two systems of tortuous heating iiues, which receive the heating gases from a'pair of lire chambers 'liflocated at the front of the oven, though the invention is i equally applicable to ovens having rear fire chambers." ranged on the right and'left side of the` oven respectively, each fire chamber being|prd vided with an ash pit 15, the lire chdlnber 'and pit being accessible through dodr 1 6;

From each fire chamber, there extendslrearwardly a pairof heating flues 17 thatlcommunicate with a transverse flue 18 f `rmed in the rear oven wall 19. The inner ehd of flue 18 communicates with a dead flue 20 disposed below the center of the baking cham'- v4ber, while the outer end of iiue 18 com.

municates with a pair of fines 21 .disposed Aalong the side walls 'of said chamber. The

heating 'gases travel from fire. chamber 514 backward through flues 17 and thence di- Specication of Letters Patent.

of the baking chamber is thoroughlyhated. The front ends of the outer iiues21'are accessible through outer and innerY lugs 22, 23, tted into front wall 12, forwar v andbackward of dead air space 13 respeetiw'fely.'` The front ends of each pair of flues'21 commu nicate with a common vuptake 24 built into front wall 12, the two uptakes in turn communicating with transversely .disposed distrlbuting chambers 25 formed in wall'12 directly beneath the roof 26 of baking chamber 10. 1 Into this chamber, enter thevforward ends of a plurality loff:longitudinally arf liangesJBO b means of which the Asleeves are anchfored. ach'pi 27 is snugly encom sleevfeaI 29, whichv while foi-ming *a reliable' Iand bearing for the pipegpermits its freetexpansion and contraetm Furth V"tially morthe :flanges 'which circ f ass the sleeves` and are setbacbfron n s thereof,r form tightjjopits'jbtween ing a distance' above and belowslichq pipes..

The upper ends of ducts 31 communicate with the rear ends of a plurality of lon 'i built into the oven directly abovethe rof .26 of the baking chamber and 'communie tingat their forward end with a transve chimn ey passage 38. .It 'will be seen that bythe construction described, the heating. gases The rear ends f of' rise from *Hues 2l through'uptalres 24int0 distributing chambers 25, 4fiow` rearward throuhwpipes 27, upward throughducts 31, and *t ence forward through fines 32 t'o be `finally discharged from the chimney. --In this .way the baking chamberv is subjected to both bottom and top heat in amost thorough and uniform manner. Access vto pipes 27 .may beobtained by outer and inner plugs fi moving the soot from t ing the soota'eeuinulating in the heating ues and pipes and which may be pushed back from time to time along saidtlues and pipes after rst removing the plugs. .For the pun pose of removing the soottrom the lower tlues 17, each transverse flue 18 Communieates oppositethe rear ends thereof, by ltwo converging branches 38 with the rear end of a gallery 39, which extends longitudinelly through the oven `from the back toward the front thereof and is located below thelevel of fines 17. The front end 'of nach' gallery 39' enters the back of ash pit 15 and is normal-ly elosedbyva plug 40. For removing the soot from the outer dues 21, Meh transverse line 18 communicates oppothe ends thereof with t-Wo converging inches lll, l2 of a downwardly extending substantially Y-shaned duct opening-,into the rear end or" a soot gallery i3 llocated in a plane beneath the lower heating fines which. 'Ul'ewise extends longitudinali through 4the oven and is arranged preferab yon thel same level with ,galleries 39'. Of these branches, the inner branch il has a pronounced outward deflection for the purpose of carrying gallery 43 Well towardthe outer side of the oven. The forward end of; gallery 43' is :ulapted to be closed by a plug 44C. For rs-- e u per pipes 2'? and ilues 39., the lower, ends o each set ot 'rear nin-ight duets 31 open into' the two branches 455, of a downwardly extending Y shaped duet 4:7, the inner branch having amore pronounced dip than the outer branch, so as to carry duct 47 toward the outer side of the oven. Duct i7 opens into the rear end o'f a longitudinally arranged soot gallery 48 aeeonunodated between ash pit 15 and gallery lli-l and adapted to be closed by a plug 49.

It will be seentliat by `the means de scribed, each ot the rear llines is tapped at a plurality of points by the Y shaped branches of the rear upright soot duets, which thus collent the soot along the `entire length of such rear lues, and cause the same to be massed within the several longitudinally extending soot galleries. Afsi thesel alleries open into the ash pits and into tie oven front sidewise of the ash pits, the soot may be readilyremoved fromv the 'oven front,A

such removal being in no Wise hindered by noemen building a battery of ovens closely side by side.

When the door ot the baking Chamber is opened While the baking going on, a considerable volume of steam issues therefrom into' the bakery to the great discomfort of the operator. n order to abate this nuisance, l provide directly above the oven door 11, a sheet metal hood 50 that projects some distance beyond the front Wall 12. ',lb' hood extends with its downwardly direc mouth directly above the openingof the baking chamber, so that upon opening door 11, the escaping steam will have a tendency to rise into the hood from whence it escapes through a by pass 51 into the chimney.

I claim: y

1. A bakers oven, comprising a baiting chamber, a plurality of heating llues er tending above and below said chamber, transverse rear lines into which the heating fines open,` sets of downwardly extending soot duets tapping the transverse dues at Va- 'ions points, said duct-s converging from their upper toward their lower ends, Where they merge into each other, a plurality of longitudinally arranged soot galleries that communicate at their rear ends with the soot ducts, while their front ends open into the oven frontfand plugs for closing said duets.

2. i-*Lbaliers oven, comprising a baking 1 chamber, a plurality of heatin tending above -and below sai transverse rear lues into which the heating flues open, sets of downwardly extending soot ducts tapping the transverse flues at various points, said. ducts converging 'from their upper toward their lower ends, Where they merge into' each other.I a plurality of longitudinally arranged soot galleries, that 'communicate at their rear ends With the soot l ducts, lire chambers haring' ash pits and l0- cated at the oven front, some or' the soot galleries opening into said ash pits, While the other soot galleries open. into tlie oven front, and plugs for closing the last named soot galleries.
